Definitions

  • the invention relates to equipment for the practice of alpine skiing, and in particular the shoes intended to be fixed in ski safety bindings.
  • the shoes for the practice of alpine skiing generally comprise a rigid shell footwear and having a sole intended to be secured to a safety binding. Such shoes are generally divided into two categories.
  • a first category of shoes is called rear entry.
  • the rigid shell has a shell bottom made of rigid synthetic material and in which a sole is formed.
  • the bottom shell forms an envelope covering the lower part of the foot and ensuring its maintenance.
  • a half-collar is attached to the upper part of the lower shell.
  • the half-collar has a wall extending continuously between the lateral edges of the shoe through the front portion.
  • the half-collar forms a support for the shin to limit the tilting of the user forward.
  • Such a shoe further has a rear wall pivotally mounted on the shell bottom. The rear wall cooperates with the collar to define an upper opening of the shoe through which the leg of the user passes.
  • a liner, introduced through the upper opening, is housed in the volume delimited by the shell bottom, the half-collar and the rear wall.
  • the user tilts the rear wall towards the rear, in order to widen the upper opening.
  • the user then introduces his foot inside the liner and ensures proper tightening of the shoe through a loop surrounding the rear wall. Once the loop is tight, the back wall provides support for the user's calf to limit its tipping back.
  • This type of shoe has many disadvantages, including the excessive stiffness of the shell, the difficulty of tightening and adjusting the interior volume of the shoe to the morphology of the foot and finally the fact that the bending forward is blocked by the presence of the half-collar.
  • a second category of shoes is called front entry.
  • the rigid shell has a shell bottom made of rigid synthetic material and in which a sole is formed.
  • the bottom shell forms an envelope covering the lower part of the foot and ensuring its maintenance.
  • a collar is attached and fixed on the upper part of the shell bottom.
  • the collar has a wall extending continuously from a first fin placed at the front of the shoe, through a first side edge, the rear portion of the shoe, a second side edge and a second fin placed at the front. before the shoe.
  • the collar thus provides a back support for the calf of the user to limit his tipping backwards.
  • the collar is a synthetic part attached to the bottom of the shell.
  • the collar is pivotally mounted about a transverse axis of the shoe.
  • the collar can rotate from front to back.
  • the pivoting of the collar may however be braked by an elastic connection formed at the pivot axis or by its engagement on the front at the instep, against the bottom of the shell.
  • the ski boot has a medial front opening extending from the kick to the tibia. This opening is constituted firstly by a first slot formed between two flaps or overlaps from the shell bottom and secondly, by a second slot formed between the two wings of the collar.
  • the tightness of the shoe is ensured by the covering of one of the flaps on the other and the covering of one of the fins on the other. To wear such shoes, the user must spread the flaps of the bottom shell and the fins of the collar, to widen the upper opening.
  • Such a shoe has a number of disadvantages. On the one hand, such a shoe is relatively expensive to manufacture. On the other hand, the formation of the pivot between the shell bottom and the collar forms a protruding part inside the shoe, which reduces the available volume for the foot of the user and can induce unpleasant localized pressure. Moreover, such a shoe is in practice difficult to put on, especially for young users who have trouble widening the upper opening introduction of the foot.
  • the document FR1587712 discloses a front entry type shoe which has a hinged upper part on the lower part by means of lateral joints and a hinged top hinged part, the latter promoting introduction of the foot without difficulty.
  • this shoe has the aforementioned drawbacks.
  • the lateral joints reduce the available interior volume or as a consequence a shoe with a large external appearance.
  • the pivot-type lateral joints are necessary when using a top part in one piece, because the upper part so rigid flexion forward that only free lateral joints (for example with pivot axis) allow to have a satisfactory ski boot.
  • flap top is also described in the document FR2371896 , for a shoe having no hinged upper part. If it is easy to put on, such a shoe remains uncomfortable and inefficient.
  • the document FR 1 587 712 also discloses a ski boot with a flap upper and a hinged collar at the malleolus.
  • the invention aims to solve one or more of the disadvantages mentioned above.
  • the invention aims to provide a shoe that is lightweight, comfortable, easy to wear, relatively inexpensive to manufacture and is suitable for use by very young children.
  • the figure 1 is a front view of the shell of a shoe 1 according to the invention.
  • the figure 2 is a front view of this shell, a clamping loop has been removed.
  • the figure 3 is a front view of this shell, a tab has been removed.
  • the liner placed inside the shell to accommodate the foot of the user in a comfortable manner, is not illustrated.
  • the shoe 1 is intended for skiing with safety bindings.
  • the boot 1 comprises for this purpose a rigid sole 21 having protuberances at the front and rear. These protuberances, called front end pieces and rear end pieces have standardized dimensions in a manner known per se for their maintenance by the security attachment.
  • the sole 21 is integrated in a rigid shell bottom 2.
  • the shell bottom 2 has a shape for wrapping the lower part of the foot of the user.
  • the shoe 1 further has a collar 3 formed integrally with the shell bottom 2.
  • the collar 3 is connected to the shell bottom by a material bridge 33 allowing its pivoting relative to the shell bottom around a transverse axis of the shoe (Y axis).
  • a collar 3 and a bottom shell 2 in one piece allows for the shell of the shoe 1 in a single injection of synthetic material, for example polyamide, polyurethane.
  • synthetic material for example polyamide, polyurethane.
  • the cost of the shoe is thus reduced.
  • such a shell allows pivoting of the collar 3 forward without using mechanical elements protruding towards the inside of the shoe.
  • the comfort of use of the shoe is improved, in particular when the material bridge 33 is located near the malleolus of the user.
  • the collar 3 and the shell bottom 2 define a front opening 22.
  • This front opening 22 extends at least between the kick of the user and the part upper shell 1.
  • the bottom shell 2 has free edges 28 and 29 defining the lower portion of the front opening 22.
  • the two free edges 28, 29 do not overlap as is the case in the shoes to " overlaps "(overlapping flaps).
  • the collar 3 has fins 31 and 32 arranged vis-à-vis.
  • the fins 31 and 32 extend from opposite side faces of the collar 3.
  • the fins 31 and 32 have free edges 36 and 37 defining the upper portion of the front opening 22.
  • the free edges 36 and 37 are spaced apart. one of the other transversely.
  • the fins 31 and 32 are not superimposed, the opening 22 separating them facilitates the introduction of the foot of the user into the interior volume of the shoe 1.
  • the fins are longer in such a way that they overlap when the collar is closed. Thus they rest on the instep and when the user bends forward, they create a progressive friction. Such progressive friction can be adapted for a ski boot whose objective is performance.
  • a tongue 4 is pivotally mounted at the front portion of the bottom shell 2.
  • the tongue 4 is pivotally mounted about a transverse axis (Y) of the shoe 1.
  • the tongue 4 is configured to close the front opening 22 As detailed later, the tongue 4 has overlapping surfaces with the fins 31 and 32.
  • the tongue 4 allows on the one hand to ensure sealing at the front opening 22.
  • the tongue 4 allows on the other hand to ensure retention towards the front of the leg of the user.
  • the surfaces 45 of the tongue 4 superimposed on the fins 31 and 32 come into friction with these fins 31 and 32.
  • the tongue 4 thus makes it possible to provide braking of the pivoting of the user's leg forward. . Due to the spacing between the fins 31 and 32, they can easily be separated from each other to provide a large front opening 22 and facilitate the insertion of the user's foot inside of the shoe 1. The insertion of the user's foot will be facilitated by a pivoting of the tongue 4 towards the front, as illustrated in the position of the figure 4 .
  • the tongue 4 has lateral surfaces 45 in its upper part 49. These surfaces 45 are superimposed on the fins 31 and 32 to improve the sealing of the boot 1 and ensure braking of the pivoting of the collar 3 forward by contact with the fins 31 and 32. These surfaces 45 are advantageously placed at the rear of the fins 31 and 32, so that when the tongue 4 is biased to be pivoted forward, it causes the transverse spacing of the fins 31 and 32 to facilitate the introduction of the foot of the user in the shoe 1. The surfaces 45 also maintain the upper portion 49 of the tongue 4 at the rear of the fins 31 and 32. The tongue 4 and the collar 3 cooperate to delimit an upper access opening to the interior volume of the shoe 1.
  • a loop 5 ensures the clamping of the collar 3.
  • the loop 5 presents in a manner known per se a support 51 fixed to a lateral face of the collar 3 and a support 52 fixed to another lateral face of the collar 3.
  • the loop 5 comprises a tightening link 53 spanning the front opening 22 at the fins 31 and 32.
  • the loop 5 allows to change the clamping of the collar 3 by bringing the fins 31 and 32 closer to each other.
  • the link 53 can be made in the form of a rack inserted in a pawl of the support 52.
  • the link 53 can be moved in a known manner by means of a lever secured to the support 51.
  • Loop 5 makes it possible to define the level of friction between the upper part 49 of the tongue 4 and the fins 31 and 32, and thus the level of resistance to the forward pivoting of the collar 3.
  • the loop 5 also makes it possible to maintain the portion upper 49 of the tongue 4 at the rear of the fins 31 and 32.
  • the clamping link 53 is fixedly attached to the collar 3 to prevent its opening. It is thus possible to prevent the user from placing the upper part 49 of the tongue 4 at the front of the fins 31 and 32. Poor positioning of the boot 1, in particular on the part of a child, is thus avoided. .
  • the collar 3 is connected to the shell bottom 2 by means of material bridges 33 disposed on the lateral faces of the boot 1.
  • These material bridges 33 are advantageously arranged in front of the position of the malleolus, in particular for shoes intended for children, in order to have greater flexibility in pivoting the collar 3 towards the front.
  • the advanced position of the material bridges 33 is clearly visible at the figure 4 .
  • the foot 61 of the user has been drawn in fine dotted line, the location of the malleolus 62 is also represented by a circle. It is admitted that the axis of the ankle joint is just below the external malleolus.
  • In the manufacture of an alpine shoe articulated rod is matched the axis of articulation of the rod with that of the articulation of the ankle.
  • the distance separating the hinge axis from the rear end of the ankle corresponds to approximately 25% of the total length of the boot.
  • This percentage “P” can still decrease for very large sizes.
  • the percentage “P” is between 30% and 40%, preferably between 33% and 38%.
  • the shoe according to the invention is a shoe having satisfactory flexibility, despite the presence of a hood (that is to say a rigid tongue) covering the entire upper face of the shoe.
  • the pseudo-axis of articulation is located at the center 64 of the bridges 33.
  • the percentage "P" is about 36%.
  • the position of the bridges 33 could for example be moved back to increase the resistance to pivoting.
  • the width of the bridges 33 may also be adapted to have adequate pivoting flexibility.
  • the collar 3 will be connected to the shell bottom 2 only via the bridges 33, to facilitate the control of the forward pivoting of the collar 3.
  • the material bridges 33 also make it possible to elastically urge the collar 3 towards a rest position, when the collar 3 is pivoted forwards or backwards.
  • Openings 35 are formed between the fins 31 and 32 and the edges 24 and 25 of the bottom shell 2.
  • the flanges 24 and 25 extend upwardly under the fins 31 and 32.
  • the openings 35 allow the passage of the portion upper 49 of the tongue 4, so that the upper portion 49 is disposed at the rear of the fins 31 and 32.
  • a superposition between the upper portion of the tongue 4, the flanges 24 and 25 and the fins 31 and 32 is performed locally. This superposition makes it possible at the same time to provide frictional braking when the collar 3 is pivoted forwards, and to ensure a better seal of the boot against the penetration of water.
  • the tongue 4 has indentations 47 formed on opposite side edges. The notches 47 are placed at the bending fold 63 of the tongue.
  • the bridges 33 are housed in the notches 47 in order to improve the tightness of the internal volume of the the shoe 1.
  • the maximum tightening of the shoe will be obtained when the bottom of the notches 47 abuts against the bridges 33. This provision prevents too strong tightening of the shoe.
  • the tongue does not include notch 47.
  • the edges of the tongue have in any case the possibility of abutting the bridges in ways to improve the seal.
  • the abutment of the edges of the tongue with the bridges offers an advantage of the shoes according to the invention for shoes intended for very young children. The tightening of the lower part of the foot can not then exceed a maximum value.
  • the Figures 5 to 7 illustrate the tongue 4 according to different points of view.
  • the front end of the tongue 4 is fixed to the shell bottom 2 by means of rivets 41.
  • the tongue 4 is thus attached to the shell bottom 2.
  • the tongue 4 has orifices 42 formed in its front end for the passage of rivets 41 or fixing screws.
  • Corresponding orifices 23 are formed in the bottom shell 2 to allow the passage of such rivets or fixing screws.
  • An attached tongue 4 may be made of a material other than the shell bottom 2 and the collar 3, to present for example greater rigidity and limit the pivoting of the collar 3 forward.
  • the tongue is injected at the same time as the shell bottom, for example by means of a material connection at its hinge. It would then be made of the same material thus achieving a more economical version of the shoe.
  • the pivoting of the tongue 4 is ensured by its deflection relative to its front end.
  • the tongue 4 advantageously has a thinning 43 above the attachment zone in which the orifices 42 are formed.
  • the tongue 4 has a lower portion 402 intended to close the opening 22 between the free edges 28 and 29 of the shell bottom 2.
  • the upper portion 49 of the tongue 4 is intended to seal the opening 22 between the free edges 36 and 37 In particular, the middle portion 44 of the tongue 4 closes the opening 22.
  • the tongue 4 has an upper end 401 for gripping by the user to facilitate its pivoting forward.
  • the tongue 4 has lower surfaces 46 intended to be superimposed on the free edges 28 and 29 of the shell bottom 2 in order to seal the boot 1.
  • beads 48 (shown in broken lines at the figure 7 ) are advantageously fixed on a lower face of the tongue 4, at the surfaces 46 to come into contact with the shell bottom 2 on either side of the opening 22.
  • the beads 48 may for example be made of material elastomer such as silicone or be made of the same material as that of the tongue.
  • a rear opening 34 is formed between the shell bottom 2 and the collar 3.
  • the opening 34 advantageously extends between the bridges 33.
  • the bottom shell has a flange 26 extending upwardly under the collar 3.
  • the flange 26 is separated from the collar 3 by the opening 34.
  • the opening 34 communicates the interior volume of the shoe 1 with the outside. Thus, if water enters the shoe through the upper opening 11, the water flows, is recovered by the flange 26, then discharged outwardly through the opening 34.
  • the transverse spacing between the fins 31 and 32 forms a narrowing 27 of the opening 22.
  • the invention is particularly suitable for shoes intended for children, for example for sizes smaller than or equal to 34 in European size.
